This invention relates to a machine for tramping cotton lint, to compress it in the press boxes of a baling machine.

An object of the invention is to provide 6 a machine of this character which will automatically feed'cotton lint into the press boxes the packer or tramper is movinginto the press box of a machine. w

A still further object of the invention is to provide a machine wherein the load is not directed to the crank shaft of the machine, until the crank of the shaft has moved downwardly to a sharp angle, to thelend that as and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without-departing from the spirit of the invention.

Referring to the drawings in'detail. the machine comprises a pair of parallel channel bars 5 which are held in spaced relation with each other by means of spacing bars 6, that are bolted to the bars :5. The body portion of the machine is indicated generally by the reference character 7, and as shown is mounted on the upper edges of the angle bars 5, which act as the support for the body portion.

Extending into the body portion is the power shaft 8 which is provided with pulleys 9 and 10 respectively, the pulley 10 being loosely mounted on the shaft 8, while the pulley 9 is keyed or otherwise secured to the shaft 8 to impart rotary motion to the shaft, when the belt 11 is moved from th idle pulley 10, to the pulley 9.

The reference character 12 designates the controlling rod that has a forked end 13 en gaging the belt, so that movement of the controlling rod 12, will move the belt, in amanner as described. Lever 14 connects with that in turn is mounted on one end of the crank shaft 17, that extends through vertical channel bars 18, the shaft 17 being mounted in suitable bearings formed in the channel bars. These vertical channel bars provide supports for the channel guides 19, that are shown as bolted to the channel bars, by means of the strap 20. As clearly shown by Figure 4 of the drawings, these tubular guides 19 are formed with elongated openings 21, through which the ends of the rod 22 extend, the rod 22 being connected withthe cotton packer or tramper posts 23, that connect with the trampers 24.

Connected with the crank shaft 17, are connectingrods25 that have pivotal connection with the rod 22, so that rotary movement of the crank shaft, will result in a reciprocatory movement of the tramper posts and, trampers supported thereby. Secured ito'the crank shaft-17, is an arm 26; that extendsupwardly herefrom, the arm being 9 provided with a roller 27 at itszfree end.

The reference character 28 designates a rodthat. has pivotal connection with one of t-the channel bars 18, at 29, the roller end of the rod 28 extending downwardly to a point near theiarm 26. Forming part of the rod 28, is a laterally extended flange 30, which I'langelies in; the path :of travel of the-roller 27 and arm 26, to be operated bythe arm 26. Connected to therod; 28 is achain 31 that moves over the pulley 32.that is sup- .portedin a bracket 38, secured to;the inner surface of the body portion or housing.

One end of thechain 31. connects with the link 34 that in turn haspivotal connections with the arm 35 mounted on theshaft 36. Secured to theshaft 3G, aresweep arms 87 thatv have. pivotal connection with the sweep board 38 which is designed to move through the curved lint chute 39,,the inner wall of' .the lint chute being formed with elongated openings 40 to allow the sweep arms to move 1 therethrough.

The spring 41 connects with the sweep board 38 and acts to normally urge the sweep board to its active position. Formed on the free edge of the sweep board 38, are spaced fingers 42 that contact with the cotton lint, to force the cotton lint through the lint chute. Thus it will be obvious'that as the crank shaft 17 moves in the direction of the arrow as shown by Figure 4 of the drawings,.the roller 27 at the free end of the arm 26 will contact with the flange 30 of the rod 28, moving the rod from a vertical position, to a position as shown by Figure 4, whereupon theroller 27 moves out of contact with the flange 30. When the rod 28 is moved. in a manner as explained, the chain30 is drawn. from a position asshown. by Figure 3 of the drawings, to the position as shown by Figure 4, resulting in thesweep board bein g moved throughout the length of the hut chute, carrying with it the lintwhich has been deposited in the lint chute by the doifing rolls 43.

On the opposite side of the machine, is a rocking arm 44 which is pivotally supported intermediate its ends, one end of the rocking arm lying in the path of travel of the roller 45 mounted at the free end of the arm 46, which in turn is secured to the crank shaft 17, to move therewith. This arm 44 is held in the guide 47, to insure the true operation thereof.

Secured to one end of the arm 44, is an arm 48 which has a downwardly extended end portion 49 adapted to engage under the shoulder 50 formed at the outer end of the spring arm 51.

'Pivotally connected to the arm-48, is an arm 52 which in turnhas pivotal connection with the arm 53 secured to:the shaft 36 on which the sweep arms .37 are secured. Thus it will be seenthatas the shaft 36 is rotated to. move the sweep board to the lower end of the lint chute, the end 49 of'the arm 48, moves against the shoulder 50,'to.hold1the sweep arm to the limit of its downward movement,

while thetramper is moving downwardly to thepress box, which in the present showing the arm 44 downwardly, until; it reaches the lower end of the guide 47, whereupon the roller moves overthe end. of the arm 44. It is of course obviousthat when the arm 44 is .moved inthis manner, the sweep arms and .sweeprcboard connected therewith, are re turned to their initial :or inactive positions,

at. the upper end of the lint chute.

.The 1 tramper which vforms an important .feature of the invention, embodies a plurality .of spaced. members 55twhich are connected bymeans of a substantiallywide board 56, to which, the. lower ends ofthe t-rampen posts .23are bolted, as byaneans of the bolts 57.

.Asclearly shown by. Figure 8 of the dr-.. v-

.ings, one-end ofieach of the spaced members -55isformed with a cut awayportmn disposed intermediatelthe side edges thereof, the cut away portions being designed to accommodate the, fingers 58, that'are secured to the-lower edge ofthe stop board 54, which fingers act toprevent.material from being forced upwardly, asthe tramper moves up- .wardly. .Extending upwardly from ,the members 55, are slats 59, which are of lengths tocover the discharge end of the lint chute. asthe tramper moves downwardly, thereby preventing material from passing fronithe line chute, intoithe press box, during the trampmg operation.

Pivot-ally mounted on the bin'GO, is an arm '61 that has a pivoted end piece 62,.which end board 38, there being provided a coiled spring 63 connected with the'end piece 62, to normally urge the end piece to a position as shown by figure 3 of the drawings. Thus it will be seen that when the sweep arms swing upwardly to the limit of their upward movement, the sweep board will be swung forwardly, and that when the sweep arms move downwardly, the sweep board will be swung outwardly to its active position.

A guard member 64: is mounted near the upper edge of the press box and acts to prevent cotton lint from being forced over the edge of the press box, as the material is being fed thereinto.

In the form of the invention as illustrated by Figure 12 of the drawings, the sweep board moves over the pivoted member 65, which is provided with a coiled spring 66 for holding the pivoted member in its positions of adjustment, the coiled spring being connected to the pivoted member in such a way as to throw the pivoted member past dead center as the sweep board moves thereover. Thus it will be seen that as the sweep board contacts with the pivoted member, the sweep board will be swung to'its active or inactive position.

A-stop 67 is formed on one end of the sweep board, to engage the sweep arm 68 and restrict movement of the sweep board. A counterbalancing weight is indicated by the reference character 66 and as shown is connected with the cable 69 that is wound on one end of the shaft 36, to the end that as the shaft is rotated to a predetermined point and released, the weight will act to counterbalance the action of the shaft.

In view of the foregoing detail description, it is thought that a further detail description as to the operation of the device is unnecessary.

I claim:

1. In a cotton lint tramper, a press box, a tramper operating in the press box, a chute for delivering material into the press box, a sweep arm operating through the chute, a pivoted sweep board on the sweep arm, a pivoted member lying within the path of travel of the sweep arm to operate the sweep board and swing the sweep board to its active or inactive position, and means for operating the tramper and sweep arm.

2. In a cotton lint tramping machine, a bin, a chute for receiving material from the bin, a press box into which the chute directs material, a sweep arm operating within the press box, sweep arms, a pivoted sweep board mounted on the free end of the sweep arm and operating throughout the length of the chute, means in the path of travel of the sweep board for moving the sweep board to its active or inactive positions, and means for operating the tramper and sweep arm.

3. In a cotton lint tramping machine, a bin, a chute for releasing material from the bin, a press box into WhlCh the chute directs material, a body portion supported above the press box, a tramper post operating through the body portion and carrying a tramper operating within the press box, a crank shaft, means for transmitting movement of the crank shaft to the tramper post, a sweep arm mounted on the body portion, a sweep board pivotally mounted at the free end of the sweep arm and operating through the chute for forcing material through the chute, and means for transmitting movement of the crank shaft to the sweep arm to 0perate the sweep arm.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
